The exciting part for me is the trop following the strat with moving the vortex over towards Siberia, we are in the game people.

Well the 192 ECM is hardly filling me with frigid joy.

Yes that'd be because you're looking at a time frame well too early for cold..

It does look even less promising than the GFS at 192 though, where the ECM usually amplifies too much, just have to hope that the caveat of GFS sometimes being better in zonal transitions to Northerlies holds true.

I hope it does actually happen but unfortunately it will count down like clockwork until day 10 and then just disappear into thin air! Hope not but that’s what usually happens.

not normally a downbeat chap so I’ll leave that there plus I suppose it’s still not even winter. 
many ups and downs throughout the coming months I’m sure

We're not looking at charts that are 14 days away for cold weather

GFS shows a cold pattern emerging at D10 with riding to the west of us pushing North

A good few ensembles also showing a similar solution

The chart you posted a few moments ago was for D8 - this has never been shown as a day with a 'cold' flow

EDIT: An acceptable chart from the ECM at +240 - signs of ridging too to the west?

While I liked the GFS 12Z operational's post-240 evolution, it's fair to say that that evolution doesn't have much support from the ensembles, so only time will tell what's going to happen...?🤔

Looks good , could be similar to the GFS Op if it went out that far. Heights opening up I to Greeny and higher NH

...I see where you are coming from! But when has the hunt for cold ever been a straight forward case that models agree on as far out as D12? If the GFS does verify it is likely to be a rocky road with twists and turns, with seeming false dawns. 

The ECM 12z has made subtle moves towards the GFS op, though not quite there yet. It has the Pacific High more in play compared to the 0z and gets an Arctic surface high but not as strong upper wedge. Also it has the GFS direction of travel with the tPV migrating to Siberia.

D10 charts:

A kind of symmetry there? It does indicate to me that the GFS playbook is not pie in the sky. Though the GFS op solution may be at the very lucky end of what the UK could get if the pattern verifies.

As I'm quite new to posting in the model thread, can I double check I am allowed to post D10 charts? 🙂

You can post day 100 charts from the CFS if they show deep cold for the U.K. 😀

Look at those rainfall spikes...or the lack of....FINALLY!!! It’s going to be dry...!!!!! For a while at least 🙂

Where we end up regarding winter wonderlands is another matter, but for me that dry period is so welcome.

Except on the rare occasions they show very cold weather!

Was just about to post yes that's more of what took my interest you can see the gfs operational a cold run with some support but some trend milder although on the surface for a while next week will be cold and at times frosty. 👍

Gem ensembles little difference..

Dry few days then more rainfall spikes and coming back sooner than the gfs but we shall see, upper air temperatures shown to be cold for the next few days then becoming milder then perhaps going back down towards average for the extended range up and down sums that up. 🙂

Thanks Knocker...

Perhaps wintry potential for elevated northern regions on the eps...

Far too early to be thinking detail. At the moment just trying to get a hold on the direction of travel

Its a significant 850mb -ve anomaly though in a 50 member suite at D15.
